Understanding Importing Classes in JSP
For a JSP newbie, utilizing Java classes beyond the built-in java.lang package can be challenging. Importing classes in JSP is necessary to utilize external classes, such as java.util.List, for instance.
Importing a Single Class
To import a specific class like java.util.List, add the following import statement to the beginning of your JSP code:
<%@ page import="java.util.List" %>
This statement informs the JSP compiler to include the List class from the java.util package.
Importing Multiple Classes
You can also import multiple classes at once using the following format:
<%@ page import="package1.myClass1,package2.myClass2,....,packageN.myClassN" %>
Substitute "package1" with the package name and "myClass1" with the class name for each class you wish to import.
Remember to place the import statement at the top of your JSP file, before any other code. This ensures that the compiler has access to the imported class when processing the JSP page.
